'300: Rise of an Empire' was originally one of our most-anticipated movies of the year ... that is, until Warner Bros. decided to push the release date back from Aug. 2 to Mar. 7, 2014. But while we await the coming bloodshed, the studio has dropped a new poster in anticipation of its upcoming panel at Comic-Con 2013.

Directed by Noam Murro and starring the likes of Sullivan Stapleton, Eva Green ('Sin City: A Dame to Kill For'), Lena Headey ('Game of Thrones'), Hans Matheson, David Wenham and Rodrigo Santoro, '300: Rise of an Empire' is based on Frank Miller's graphic novel 'Xerxes.' From the officially released plot synopsis:

This new chapter of the epic saga takes the action to a fresh battlefield -- on the sea -- as Greek general Themistokles attempts to unite all of Greece by leading the charge that will change the course of the war. '300: Rise of an Empire' pits Themistokles against the massive invading Persian forces led by mortal-turned-god Xerxes, and Artemisia, vengeful commander of the Persian navy.

The '300: Rise of an Empire' Comic-Con panel will be held in the buzzing Hall H on Saturday, Jul. 20, along with other Warner Bros./Legendary Pictures properties 'Seventh Son,' 'Godzilla,' 'Gravity' and 'The LEGO Movie.' We'll be on hand to bring you the latest updates, but in the meantime, check out the new poster below.
